Application filed June 16, 1916. Serial No. 104,059.

To all whom it may concern:

Be it known that we, (1) ADAM RICHARD son and (2) BERT B. JACKSON, citizens of the United States, residing at (1) Elba, (2) Almyra, in the county of (1) Van Buren, (2) Arkansas, and State of Arlmnsas have invented certain new and useful. Improve ments in Work-Supports; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to a wheel. boring machine.

spoke tenons.

The object of the present invention is to improve the construction of wheel boring machines and to provide a simple, practical and. comparatively inexpensive device of this character adapted to be readily applied to the post or support of a force teed drill or boring machine and equipped with a combined support and spindle ,adapted to re ceive either the hub or fellyof the wheel and capable of rapid and accurate adjust ment to arrange the wheel in proper position with relation to, the drill or boring machine and capable of enabling tenons to be accurately and uniformlybored on the ends of spokes and of boring accurately the holesin follies for the 1 receptii'm of the With these and other objects in view, the invention'consists in the construction and novel (zombination of parts hereinafter fully described, illustrated in the accompanying drawings and ointed' out in the claims hereto appende it being understood that various changes in the form, proportion, sure same,

Fig. 4*is a vertical sectional view of the Fig. 5 is a transverse sectional View of a spindle, the hub being shown in position,

Fig. 6 is a detail perspective new of the post plate,

Fig. 7 is a similar View of one of the ad justable felly gages,

Fig. 8 a detail view illustrating the manner of tenoniny; a spoke,

Fig. 9 is a detail perspective view of one of the arms.

Like numerals of reference designate corresponding parts in the several figures of the drawings.

In the accompanying drawings in which is illustrated the preferred. embodiment of the invention, 1 designates a post plate preferably consisting of a casting and bolted or otherwise secured to a postil below a force feed drill 3 and provided at opposite sides of its center with vertical slots 1 through which extend arms 5 of a combined support and spindle 6 adapted to receive the hub 7 or felly 8 of a wheel. and capable of vertical adjustment to arrane the folly and the hub in proper position with relation to .the'drill. The drill as illustrated in Fig. 8 is also adapted for operating on the spokes 9 for boring tenons which may be accurately and uniformly made to fit the holes bored in the. telly 8. The poet plate is preferably provided at the back with cored central and side recesses 10 and 11 both to lighten the construction and also to provide clearance spaces for the heads 12 of the arms 5. The heads 12 form laterally projecting lugs 13 which have rounded front faces 14 to bear against the-inner or rear face'ofthe post plate at opposite sides of the vertical slots d.

The post plate is machined or otherwise dressed to form smooth true faces at the slots and the arms 5 are provided with inner and outer slots 15 for the reception of bolts 16 having nuts 17 for engaging the outer faces of the arms which are provided with. corrugations 18 whereby the bolts and nuts are effectually prevented from permitting any accidental slipping of the spindle or support. The spindle or support is adjusted by means of the bolts 16 and slots 15 to compensate for any wear of the parts and arrange the spindle at the proper pitch or in clination when such adjustment is necessary.

The support or spindle which is tapered outwardly t0 fit the axle-box of thehub is preferably constructed of hard wood butit ma bemade of any other suitable inaterial .-an it is "equipped at its inner or rear end with a heel plate 19 suitably secured to the indle or su port and provided at its lower dge witha veled rib or enlargement 20, which is adapted to engage spiral or rasp teeth 21'forn1'ed on the front face of the post plate and extending across the space betweenthe vertical slotsand presenting horizontal upper faces or shoulders and inclined lower faces. By this construction the transverse rib or tooth;which is located below the horizontal plane'of the heads of, the arms is adapted to be readily swung forwardly out of. .engagement'with the rasp face of the 1' post plate by-lifting the'outer portion of-the Spindle. This'will enablethe spindle to be easil I and quickly adjusted and arranged at.

the esired elevations The post plate is provided at the-space between one of its vertical 7 slots and its side edges with graduations 22 "understood.-

The support or spindle is provided inits 'Touterportion with a vertical opening 23 adaptedto receive the drill bit and ithas a: recess 24 in its upper face presenting a flat face to'a' felly toform ,a thereforpreferably cast in the surface of the post 'plate butthey may be applied to the same in other desired manner as will be readily -..,and'rece1ving' a. pair of felly gages 25. The

any gages 25 each consist of a plateor bod jportionprovided with an upwardly exten 8 "b -';a be t-27operatingin a-slot'28;in.the -p ftepor body portion 2- and J'ng flan e 26 and secured inits' adjustment i ing the or support and provided mtslower end with' an adjusting" nut ,29 which is countersunk in a lower recess 30 in the lower.- faoe of the spindle or support. The felly I gages are adapted to be adjusted to suit the width of a felly and they are provided with ribs main- 1011 for acingin grooves 32. The lug tam the gages in proper p curately guiding the folly so that the tenon receivin openings will be true. The gages located within the contour of the spindle central longitudinal ribs or lugs 31 operat-- and their flanges which are segmental are or support and a hubis adapted tobe passed over them without contact with either the gages 'or' fastening ineansfor securing the gages in their adjustment.

What is claimed is L-A work holder including a spindlearranged v to receive and support the hub of a wheel, said spindlebeing provided between its ends with a felly rest located with :in the contour of the spindle to permit a hub to pass over it;

2. A work holder including a spindle arranged to receive and support the hubof a wheel; said spindle being provided between t 5 its ends with a recess forming a felly rest,
